Accurate, complete fuels data are critical for making fuel management decisions and for predicting fire behavior and fire effects. A fuel photo series is a useful reference that allows natural resource managers to quickly quantify fuel and vegetation properties by comparing on site conditions to a series of photos showing a range of calculated fuel loads within a similar vegetative community. While there are photo series available for a wide range of ecosystem types nationwide, this type of information is lacking for natural and mechanically treated chaparral. The most likely reason for this information gap is the difficulty in collecting and photographing fuels in these dense fuel types. The attached PDF document is a series of [...]

The fuels and vegetation data accompanying this photo series were collected for a Joint Fire Science Project looking at the effects and effectiveness of mechanical treatments in chaparral. This study, which quantified fuel composition and structure, provided a unique opportunity to capture photographs of a range of treatments across a variety of chaparral types on the four southern California national forests.
